What are the lecture rooms and laboratories like? I have yet to visit KCL on an open day, will I get an opportunity to see rooms in their normal state...or is this hidden from prospective students?
If anybody knows how the physics department is in particular, it'd be very helpful. Thanks!

If you visit on an open day, chances are you won't get to see much because it is likely that the rooms will be in use. Lecture theatres and labs for biosciences are very good, and I should imagine that for physics the facilities would be similar. Do you know what campus it is taught at?
